We bought a vacation home a few years ago where the previous owner really liked air vents. Now that we're thinking of renovating a bit, we plan to remove one of the vents because its location won't work well with the planned changes to the layout. Anyway, I removed the fresh90 vent and saw that the pipe goes through the bottom of the load-bearing beam. The person who installed the vent has drilled a little less than half the hole through the load-bearing beam. Personally, I don't think this should be a problem since the beam is quite high anyway, but it is, after all, at the bottom where most of the force is concentrated. Therefore, I want to address this somehow before sealing the hole and I wanted to check here if you have any tips on how I can reinforce the beam to withstand the pressure The other vents in the house are not problematic!
I don't understand what you mean by bärlina in an outer wall. Is it a beam over a window opening, or are you using the word in a way that I'm not familiar with? Normally it is inappropriate to make notches in the underside of beams.
I guess it's the upper standing rule in the example image below that is being referred to. In that case, it would be interesting to know if there's any significant load coming from above in the compartment where the cutout is.
I also believe that it is something similar to the upper beam seen in Bernieberg's picture that TS means. In this case, I think you can say that it is significantly over-dimensioned and can therefore withstand a small cutout. However, in principle, I believe the question is too important to be overlooked. The least one should do is check that the remaining amount of wood is sufficient for the current loads. It's worth considering that the really large roof loads in the form of snow can occur quite rarely. A hole in the middle of a section at the beam's center is often better than one at the bottom edge.
It should be the horizontal beam at the top that I mean. There's a window about 20 cm to the right of the hole, so it could also be the beam that the hole has affected. As I said, I don't think there are any issues, but is there any way to reinforce it anyway before I patch up the hole?
I would preferably like to see a photo of the hole drilling before I say too much. In many cases, it can be an advantage to glue a round piece of wood with the thickness of the stud in the hole.
To really get an idea of what has holes drilled in it, the wall must be torn down, either from the outside or inside. If it needs reinforcement, you're back to tearing down some wall.
If the house is built in the 60s or later (typical)
The load-bearing beam (hammarband) is usually 45 mm thick x ------. It can be placed on its edge or lying down, or both variants simultaneously.
This if self-supporting trusses are used.
Might have to take a picture when I'm back in the house again! In the worst case, maybe it would work to tear out some panel boards from the outside and reinforce with an extra beam under the hole? The house has been standing for a few years with this hole and has withstood several heavy decimeters of wet snow, just last week
... fresh90 valve and saw that the pipe goes through the underside of the beam. The person who installed the valve has drilled slightly less than half the hole through the beam.
We are talking about a maximum removal of 0-40 mm, shaped like a circle.
Surely this can't significantly affect the load-bearing capacity of the wall overall...
Or am I missing something that the rest of you are reading??
I guess it's all right but I haven't really figured out how it looks. If you paint the devil on the wall, a rostrum can rest right between two wall studs, and the beam can have a 100 mm hole at the bottom, right under the load. As mentioned, a picture would be valuable.
The other vents in the house are not problematic!
